# Package net.sf.saxon

This package provides the core classes of the SAXON XSLT library.

See: Description

- Interface Summary
  Interface | Description
  --- | ---
  Platform | This interface provides access to methods whose implementation depends on the chosen platform (typically Java or .NET)
  TypeCheckerEnvironment | An abstraction of ExpressionVisitor that provides the minimal set of services needed by the TypeChecker; used to allow run-time type-checking of higher order function arguments without retaining the whole static context

- Class Summary
  Class | Description
  --- | ---
  Configuration | This class holds details of user-selected configuration options for a set of transformations and/or queries.
  Configuration.LicenseFeature | This class contains constants representing features of the software that may or may not be licensed.
  Controller | The Controller is Saxon's implementation of the JAXP Transformer class, and represents an executing instance of a transformation or query.
  Filter | Filter is an XMLFilter (a SAX2 filter) that performs a transformation taking a SAX stream as input and producing a SAX stream as output.
  IdentityTransformerHandler | IdentityTransformerHandler implements the javax.xml.transform.sax.TransformerHandler interface.
  PreparedStylesheet | This PreparedStylesheet class represents a Stylesheet that has been prepared for execution (or "compiled").
  Query | This Query class provides a command-line interface to the Saxon XQuery processor.
  TemplatesHandlerImpl | TemplatesHandlerImpl implements the javax.xml.transform.sax.TemplatesHandler interface.
  Transform | This Transform class is the command-line entry point to the Saxon XSLT Processor.
  TransformerFactoryImpl | A TransformerFactoryImpl instance can be used to create Transformer and Template objects.
  TransformerHandlerImpl | TransformerHandlerImpl implements the javax.xml.transform.sax.TransformerHandler interface.
  Version | The Version class holds the SAXON version information.

## Package net.sf.saxon Description

This package provides the core classes of the SAXON XSLT library.

Some of the more important classes are listed below:

`Query`:
This is the command line interface to the XQuery processor, allowing you to run a supplied query against a given source document.

`Transform`:
This is the command line interface to the XSLT processor, allowing you to apply a given stylesheet to a given source document.

`Configuration`:
This class holds all the Saxon configuration information, and acts as the fundamental factory class holding central resources and creating components such as validators and serializers.

`PreparedStylesheet`:
This represents a compiled XSLT stylesheet in memory. It is Saxon's implementation of the `javax.xml.transform.Templates` interface defined in JAXP 1.1

`Controller`:
This class represents the context information for a single execution of an XSLT stylesheet, and allows the application to process the tree navigationally. It is Saxon's implementation of the `Transformer` interface defined in JAXP 1.1. It calls user-supplied handlers registered with the RuleManager.
